IKOFLEX 1

[anthonym3]

I have a post war IKOFLEX 1 with coated TESSAR T,with a curious quirk. The shutter fires correctly except for 1/10 sec which snaps closer to 1/00 sec. Does anyone know why and is it an easy fix? I've tried moving the indicator in tiny increments but it still snaps at about 1/100.

The shutter needs a CLA. It has to do with the travel of one of the levers in the timing delay mechanism at that position. There is the main delay movement dependent on the gears running and the tension applied to the pallet.
A combination of the two are used for each speed.

Thank you for the prompt reply. Can you or anyone recommend a qualified reliable repair person?

How are 1/2 and 1/5?

The 1/10 being fast usally means that the other slow speeds are also fast. Are 1, 1/2, and 1/5 accurate? It doesn't take much all in all. 1 second can be .9, 1/2- 0.42, and 1/5- 0.18 and it can indicate it being enough off to throw 1/10 to the hyper speed (basically the pin is pushed to the limit, cutting out the slow speed escapement AND a good hunk of the high speed delay). If the other slow speeds are all good, you can file the sped file back at the 1/10 spot. You'd be amazed how little it takes to send the 1/10 into this type of hyperdrive.

Easy? Are you comfortable going inside? If so, then somewhat easy. The basic sequence for setting a Compur Rapid (?) shutter is to pivot the escapement to get an accurate 1 second. Then bend the pin to get 1/10 accurate. Then swedge or file the speed dial to fine tune other speeds.

Also a good time to ask yourself, how many times will you be using 1/10 second?

Dan,other speeds sound accurate it is only the 1/10 speed that is off. Good point regarding use of 1/10,probably not at all. I was asking mainly because I may sell it but felt it could be detrimental to sale prospect.

So you aren't measuring the other slow speeds? Realize that the effect seems to be cumulative in a weird way. If 1 is ever so slightly slow and the pin adjustment is slightly fast, by the time you get to 1/10 it's doing what you describe.

All in all it's usually not worth paying for a repair for resale unless you are looking at Leicas or other high end cameras. A shutter cleaning and adjustment will run $70 and up. Most likely here are other things to be done, and shipping. So you put $100 plus in on top of your purchase price and get $150 back. Going in yourself makes sense. Paying for repairs for sale is a labor of love more often than not. All in all most people buying an Ikoflex are not looking to shoot at 1/10 too much? Or willing to go in and do some tweaks. So you can get $100 and they can do the labor?

Maybe shutterfinger is on to something with dirt and such. If the camera is new to you I might give some good exercising and see what happens.

The other slow speeds sound reasonably accurate judging from 60 years using various cameras,NIKON,CONTAX.LEICA,etc. So I will try to sell it,of course describing the defect.
